The Apothecary Diaries has locked its return date. The official site rolled out a new trailer confirming Season 3 premieres October 2, 2026, alongside more cast and the opening theme — the concrete details fans have been waiting on since the sequel was announced. Here is what the new footage actually tells us.
Quick answer
The Apothecary Diaries Season 3 premieres October 2, 2026. The new trailer adds cast and confirms the opening song, continuing OLM's adaptation of Natsu Hyuuga's novels about Maomao, an apothecary solving poisonings and intrigue inside the imperial rear palace. It streams on Crunchyroll. For the full where-to-watch and ranking rundown, see our Apothecary Diaries Season 3 guide.
What the trailer shows
The footage leans into the palace-mystery register the series is known for — Maomao back in her element, new faces at court, and a tone that stays closer to detective drama than to romance despite the slow-burn with Jinshi. The opening-theme reveal and the October 2 date are the headline; everything else is a mood-setter for the fall slot.
